Abstract
Twelve chemicals and commercial disinfectants were tested for inactivation of equine infectious anemia virus. In the presence of 10% bovine serum, all chemicals inactivated 4 log10 (based on 0.1 ml) of the virus within 5 min at 23.degree. C. A reduction of at least 4 log10 was observed when the virus was exposed for 1 min to substituted phenolic disinfectants (3 commercial preparations and sodium orthophenylphenate), halogen derivatives (iodophor and sodium hypochlorite), chlorhexidine and 70% ethanol. Sodium hydroxide (5%), 2% formalin and 2% glutaraldehyde were slower to inactivate the virus, but achieved 4 log10 reduction in titer by 5 min contact time. The susceptibility of the equine infectious anemia virus to chemical disinfectants is similar to that of other enveloped viruses.
